Spiromesifen; Pesticide Tolerances

This regulation establishes tolerances for the inadvertent or indirect combined residues of spiromesifen (2-oxo-3-(2,4,6- trimethylphenyl)-1-oxaspiro[4.4]non-3-en-4-yl 3,3-dimethylbutanoate) its enol metabolite (4-hydroxy-3-(2,4,6-trimethylphenyl)-1- oxaspiro[4.4]non-3-en-2-one), and its metabolites containing the 4- hydroxymethyl moiety (4-hydroxy-3-[4-(hydroxymethyl)-2,6- dimethylphenyl]-1-oxaspiro[4.4]non-3-en-2-one), calculated as the parent compound equivalents, in or on the following commodities from crops grown as rotational crops: bulb vegetables. Bayer CropScience requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
